On-line wall thickness detection mechanism for cable production

The utility model belongs to the technical field of cable production, and particularly relates to an online wall thickness detection mechanism for cable production, which comprises a pipe used for wrapping and protecting a cable core, a support frame used for supporting the pipe and facilitating wall thickness detection is arranged below the pipe, and the upper surface of one end of the support frame is provided with an adjusting clamping groove; an automatic clamping mechanism is arranged on the surface of the supporting frame and comprises a vernier caliper arranged above the pipe, the vernier caliper makes contact with the outer surface of the pipe to be clamped after being adjusted up and down, and therefore the vernier caliper can measure the wall thickness of the pipe. According to the online wall thickness detection mechanism for cable production, a piston rod of a push cylinder works to push a vernier caliper to perform height adjustment, so that an upper abutting pulley and a lower abutting pulley cl
